Ask HN: What would you want in a web app template?

After submitting a WordPress theme to ThemeForest and having it get declined, I decided to gather all my themes and sell them myself. I built and launched "themESC" (http://themesc.com) in a day.

I got really great feedback and encouragement from HN (http://news.ycombinator.com/item?id=2014428).

Because all I currently have on there are WordPress themes, one of the suggestions I received was to build HTML/CSS templates sans the WordPress for web apps.

So, if you were buying a HTL/CSS template for your web app/ web biz, what would you expect it to have?
